IMPROVEMENT IN MOLD-BOARDS FOR PLOWS.

Specification forming part of Letters Patent No. 57,463, dated August28, 1866.

To all whom it may concern:

Be it known that I, GEORGE A. BEARD, of Gavetown,in the county ofWashington, in the State of Maryland, haveinvented an Improvement to theMold-Board of the Plow; and I do hereby declare that the following is afull and exact description thereof, reference being had to theacconpanying drawings, and to the letters of reference marked thereon.

The nature of my invention consists in the elevation and enlargement ofthe mold-board of the plow, so as to prevent choking when plowing amongbriars, weeds, and tall grass; also, to more thoroughly and completelyturn the furrow, and throwing all the ground loosened clean over, notpermitting any to fall over the top of the mold-board into the furrowbehind the plow.

To enable others skilled in the art to make and use my. invention, Iwill proceed to describe its construction and operation.

I construct my plow in any of the known forms of the plow. Themold-board is extended and continued as high as the collar on which thebeam rests. Said elevation is symmetrically carried back to the heel ofthe moldboard, so as to make the top or upper edge of the same rangeflush with the bottom of the beam, and then gradually and symmetricallyslope backward until it terminates behind and beyond the handle higherthan the top of the beam.

Figure 1 is a representation of a plow with my mold-board.

Fig. 2 is a represention of a plow with the moldboard of the ordinaryheight.

Fig. 3 is a representation of the mold-board. Letter a is the collar onwhich the beam rests. Letter b is the body of themold-board. Letters6,61, 6, and f show the elevation and extension, as described andclaimed above.

Fig. 4 is a representation of a mold-board as ordinarily made, by way ofcontrast.

What I claim as my invention, and desire to secure by Letters Patent,is-

The elevation and enlarged extension of the mold-board of the plow, asdescribed above, and nothing else or more.

GEORGE A. BEARD.
